Nasdaq Sets Second Straight Record Close, Up 0.45% to 27,244.28

The divergence matters more than the record itself: chip and AI infrastructure names are carrying the index while banks and energy drag on the Dow, so the rally is narrow rather than broad. That concentration cuts both ways — it signals where capital is currently flowing, but it also leaves the Nasdaq more exposed if that single theme cools. Whether the S&P and Dow catch up or the AI trade keeps doing all the work is the open question.
